The relationship between exercise and sleep quality is well-established. Regular physical activity promotes deeper and more restorative sleep by reducing sleep onset latency and increasing total sleep time. Exercise helps regulate circadian rhythms and can alleviate symptoms of insomnia. However, the timing and intensity of exercise matter; while moderate activity is beneficial, vigorous exercise close to bedtime may have the opposite effect. Overall, incorporating physical activity into daily routines can enhance the quality of sleep, fostering better recovery and health.
